<DT><B>Description</B><DD>
circle draws a circle in the current drawing color with its center at (x,y) and the radius given by radius.
<P>
The linestyle parameter does not affect arcs, circles, ellipses, or pie slices. Only the thickness parameter is used.
<P>
If your circles are not perfectly round, adjust the aspect ratio.
